They are regions of the Galaxy made of accumulated gas, dust and plasma. Their mainly chemical elements are Hydrogen and Helium. Hydrogen is its primary component, present in a variety of states, depending on the characteristics of each cloud.
Scientists used to believe that due to density and low temperatures of these clouds, chemical reactions and production happened slowly. However, organic molecules found on them suggest that it happens much faster. Since laboratories requite really high temperatures and pressure to produce them.
By the clouds being so cold, the dust is covered by ice. These grains will clutch and increase size, forming celestial objects in the Universe.
